The problem is that Google has become so pervasive that even if you don't initiate any contact with them or use any of their products/services, a bad review on Google can have a substantially negative effect on your business. It's a real problem.

I was recently in charge of hiring various contractors for several repairs needed on a house being prepped for sale, and in almost every case, clearly non-technically-inclined people were practically begging me to leave them a positive Google review. I don't think they would've been doing that if they hadn't experienced a direct impact on their business from those reviews in some way, and I also don't think they would've chosen this situation voluntarily.
